The .380 ACP (9×17mm) (Automatic Colt Pistol) is a rimless, straight-walled pistol cartridge developed by firearms designer John Moses Browning. The cartridge headspaces on the mouth of the case. It was introduced in 1908 by Colt, for use in its new Colt Model 1908 pocket hammerless semi-automatic, and has been a popular self-defense cartridge ever since, seeing wide use in numerous handguns (typically smaller weapons). Other names for .380 ACP include .380 Auto, 9mm Browning, 9mm Corto, 9mm Kurz, 9mm Short, 9×17mm and 9 mm Browning Court (which is the C.I.P. designation). It should not be confused with .38 ACP.

    SHTF ... only armed with pocket pistols?

    So, my beloved and I are up in Eugene for the very wacky cocktail party, of sorts. Alas, this one was not nearly as delightful as the last one, though we had fun together. There will be other antics in the summer months, including trips farther north, so other adventures are on the way, but I...
